~
dated May 14,1984 (same subject).
Gentlemen:
By Reference I we provided you with a comprehensive update of the status of environmental qualification activities at Calvert Cliffs.. In' that letter we identified
.several pieces of. equipment that have not yet been qualified and for these items we
.provided. a discussion justifying continued plant operation until qualification 'could be established. For each piece of equipment we r_equested relief from' the qualification deadlines. imposed by.10 CFR 50.49(g), ~ as necessary, in order to accommodate procurement and installation activities.. Replacement of certain safety-related Fischer
- and Porter. transmitters inside the Unit I containment building was identified as the only remaining qualification activity that would require - performance during. a plant.
shutdown.
Consequently, we
~
requested an. extension for replacement of these -
trar:,mitters until April 30,1985; a date which corresponds to the scheduled beginning of the spring 1985. refueling outage. In addressing this item we stated in Reference I that the }ustification for. continued operation (3CO) associated with the interim use of these
- transmitters was provided in our submittai dated February 26, 1982 as amended on February 10,1983.
..On June 6,1984' we were verbally informed b'y our NRC Project Manager of a I
conflict between the information' provided:In Reference 1 and the above-mentioned '
-l usubmittal:: regarding the ' status of the unquallfled Fischer and Porter transmitters.~
Specifically,'our letter of February 10,1983 clearly stated that the subject transmitters Inside the Unit I containment building had already been replaced.
Please be informed that we have reviewed the status of work completed l
during.the fall 1983 linit I refueling outage and have confirmed that the requisite
-activities'had~1ndeed been successfully completed. A check was also performed on the i

- Mr. H. R. Denton. June 8,1984
' status of' safety-related Fischer and Porter transmitters located in potentially harsh
~
= environments outside containment'at both Units 1 and 2 to ensure that the required qualification activities.had been completed. Based on the results of these checks we find that qualification for' safety-related. transmitters is nr y complete.. Consequently, we hereby withdraw our'May -14,:1984 request for extension regarding Fischer and Porter-transmitters; LPlease accept our apology for any inconvenience that this oversight may have caused.
~
. This letter in no way reduces or eliminates the need for the other extension requests that were the subject of Reference 1.
Your. continued attention to these-
~
matters would be appreciated.
. ith regard to the hydrogen purge system control valve W
(MOV-6902), we hereby amend our extension request to allow an additional month (until July 31,.1984) to compleie qualification. This additional time is required because of the level of manpower that has been committed to the current Unit 2 refueling outage.
